2 UV Light-Curable Adhesives, Coatings, and Encapsulants for Electronic Assembly

Our Technology. Your Advantage.

At Dymax we combine our product offering with our expert knowledge of light-cure technology. Where others only supply products, we are committed to developing a true collaborative partnership, bringing our total process knowledge to our customer’s specific application challenges.

Because we understand the process as a whole, and not just individual aspects of it, we can offer our customers a solution where chemistry and equipment work seamlessly together with maximum efficiency. Our application engineering team works side-by-side with our customers, providing assistance with testing, evaluation, and equipment selection if needed.

UV Light-Curable Adhesives, Coatings, and Encapsulants for Electronic Assembly 3

Dymax Materials for Electronics Assembly

Dymax one-part, solvent-free, UV light-curable electronic materials cure in seconds upon exposure to UV/Visible

light and can be used in a wide variety of applications for circuit protection and electronic assembly. The products

are electrically insulating and are designed for various operations including conformal coating, encapsulation,

bonding, keypad coatings, thermal management, masking, and display bonding and lamination. Most products are

available in multiple-viscosity grades, so the material flow may be tailored to the individual application. For

shadowed areas, several cure options are available, including Dual-Cure light/moisture cure and Multi-Cure®

light/heat cure technologies. IPC approved, MIL-I-46058C, and UL listed self-extinguishing grades are also

available.

Environmental Benefits of Dymax Light-Curable Materials

Dymax understands that safe, ecologically friendly products benefit our customers, the environment, and us. We have created materials with attributes that lower product costs, life-cycle costs, and ecological impact. These attributes include: Solvent-free materials Halogen-free materials RoHS compliance REACH - no substance of very high concern (SVHC) Eco-friendly, one-component materials

Dymax Halogen-Free conformal coatings, encapsulants, and adhesives are documented by an independent laboratory to meet or exceed standards set forth in IEC 61249-2-21. This international directive defines halogen-free as <900 ppm for chlorine, <900 ppm for bromine and <1,500 ppm total level of both combined. The current test method used for certification is BS EN 14582:2007.

Dymax Adhesive Technologies

See-Cure Technology

Dymax light-curable adhesives with patented See-Cure technology have built-in

cure validation that makes it easy for operators or simple automated inspection

equipment to confirm cure without investing in additional specialized equipment.

See-Cure technology is an indicator of cure that intentionally transitions the color

of the adhesive after it has cured and builds a visible safety factor into the

assembly process.

Ultra-Red™ Fluorescing Technology

Ultra-Red™ fluorescing technology, formulated into Dymax adhesives, enhances

bond-line inspection processes and product authentication. The adhesives

remain clear until exposed to low-intensity UV light at which point they fluoresce

bright red. This is particularly effective while bonding plastics that naturally

fluoresce blue, such as PVC and PET. Ultra-Red technology also produces a

unique spectral signature that can be used by manufacturers for product

authentication.

Multi-Cure® Light/Heat-Cure Technology

Multi-Cure adhesives combine the high-speed cure of UV or UV/Visible light with

secondary cure mechanisms that enhance polymerization. Secondary cure

mechanisms, which include thermal (heat) cure or activator cure, are useful when

light can only reach a portion of the bond line, or when tacking a part prior to

thermal cure to allow easier handling and transport during the manufacturing

process.

Dual-Cure Light/Moisture-Cure Technology

Dual-Cure coatings are formulated to ensure complete cure in applications where

shadowed areas on high-density circuit boards are a concern. Previously, areas

shadowed from light were managed by selective coating – eliminating the need to

cure in shadowed areas – or a secondary heat-cure process. Shadowed areas

cure over time with moisture, eliminating the need for that second process step

or concerns of component life degradation due to temperature exposure.

LED Light-Curable Adhesives

Dymax offers specially formulated LED light-curable adhesives for use with

Dymax LED UV/Visible light-curing systems. The adhesives range from fast to

ultra-fast cure speeds in order to accommodate specific electronic assembly

needs.
